dynamic behavior of factory class
- by manu1001
I have a factory class that serves out a bunch of properties.
Now, the properties might come either from a database or from a properties file.
This is what I've come up with.
public class Factory {
    private static final INSTANCE = new Factory(source);
    private Factory(DbSource source) {
        // read from db, save properties
    }
    private Factory(FileSource source) {
        // read from file, save properties
    }
    // getInstance() and getProperties() here
}
What's a clean way of switching between these behaviors based on the environment.
I want to avoid having to recompile the class each time.
